Fibrin immobilization vestibular extension (FIVE): A case series

paythelady.61 shared this article with you from Inoreader Fibrin immobilization vestibular extension (FIVE): A case series Via Clinical Implant Dentistry and Related Research Abstract Aims The objective of the present case series is to report on the rationale, surgical technique and outcome of a protocol for peri-implant mucosal phenotype modification therapy, referred to as "fibrin immobilization vestibular extension (FIVE)". Material and Methods The protocol utilized entailed apical positioning and stabilization of peri-implant flap with modular screws. The screws were also used for the immobilization of solid matrix platelet-rich fibrin to fill the gap created between apically positioned flap and the crestal margin of the flap. Results A total of 30 patients (12 male, 18 females) with 93 implants were treated with FIVE protocol for various indications, including for vestibular extension following alveolar ridge augmentation (N = 6), preprosthetic (N = 9), postprosthetic (N = 2), and peri-implantitis (N = 13). The keratinized mucosal width preoperatively was 1.67 mm with 95% confidence interval [CI] (1.46, 1.88). Immediately following FIVE surgery, the vestibule was extended to 9.10 with 95% CI (8.44, 9.76). At 3 months, 4.9 mm (95% CI: 4.5–5.2 mm) of peri-implant keratinized mucosal width was present. The keratinized mucosal width remained relatively stable thereafter and was 4.0 mm (95% CI: 3.5–4.5 mm) at 3 years post-FIVE surgery. When overall group means across all time points were analyzed, maxilla had mean of 6.1 mm (95% CI: 5.8–6.5) versus mandible exhibited mean of 5.1 mm (95% CI: 4.6–5.6 mm). The mean of maxilla was si gnificantly higher than that of the mandible (p < 0.0001) across all time points. Treatment of peri-implantitis with FIVE lead to significant pocket reduction and wide band of keratinized mucosa. Seven of 38 implants in 3 of 13 peri-implantitis patients were removed due to advanced peri-implantitis. Discussion The present case series provides proof-of-principle data for efficacy of FIVE for peri-implant phenotype modification therapy that generated attached keratinized mucosa in a variety of applications. This protocol provides an alternative to procedures involving harvesting of autogenous mucosal graft. View on the web Inoreader. Take back control of your news feed.

Acromegaly

a.sfakia shared this article with you from Inoreader Acromegaly Via Otolaryngologic Clinics of North America Acromegaly results from excessive secretion of insulinlike growth factor-1 and growth hormone, which most commonly occurs because of pituitary somatotrophinoma. Diagnostic features of acromegaly include elevated insulinlike growth factor-1 and growth hormone; lesion on brain MRI; and clinically dysmorphic features, such as soft tissue swelling, jaw prognathism, and acral overgrowth. Transsphenoidal resection is the primary therapy for individuals with acromegaly, even in the cases where gross total resection is not possible because of parasellar extension and cavernous sinus involvement. For recurrent or persistent disease after resection, systemic medications and stereotactic radiosurgery are used. View on the web Inoreader. Take back control of your news feed.

Improvement of performance and function in respiratory protection equipment using nanomaterials

xlomafota.13 shared this article with you from Inoreader Improvement of performance and function in respiratory protection equipment using nanomaterials Via Latest Results for Journal of Nanoparticle Research Abstract Nanotechnology has become one of key areas for the current development and research. Nanotechnology focuses on matter at the nanoscale and is capable of using different approaches to produce nanomaterials, structures, devices, and systems. One of the concerns that have to be addressed is the adverse effects of exposure to pathogens and pollutants in different workplaces and environments. Respiratory protective equipment (RPE) is one of the personal protective equipment (PPE) utilized to reduce the risk of exposure to environmental or occupational respiratory hazards. Thus, various studies have been conducted for improving the functional properties of sorbents or filters in different kinds of RPE. Different categories of nanomaterials have been reported as effective agents for achieving this goal. The application of these nanomaterials in mask layers or respirators' cartridge could significantly increase the filtration efficiency, breathing comfort, and antiba cterial/antiviral properties of the masks and respirators. The present study aimed to comprehensively review the nanomaterials used in different types of face RPE with emphasis on various properties of the utilized nanomaterials. The study also aimed to show an applied perspective for future research on this important subject. Graphical abstract View on the web Inoreader. Take back control of your news feed.

How I do it: management of M2 tear injury caused by drilling during intradural anterior clinoidectomy for microsurgical clipping of intracranial aneurysms

xlomafota.13 shared this article with you from Inoreader How I do it: management of M2 tear injury caused by drilling during intradural anterior clinoidectomy for microsurgical clipping of intracranial aneurysms Via Latest Results for Acta Neurochirurgica Abstract Background High-speed drilling is associated with potential injury to neurovascular structures, particularly during intradural drilling of the anterior clinoid process. Method During an anterior clinoidectomy, a cotton patty and middle cerebral artery branches became inadvertently wrapped around the bit, causing a tear on the inferior M2 trunk. Following temporary clipping of the internal carotid artery, the tear was identified. Temporary clips were placed proximally and distally. The tear was then repaired with interrupted microsutures. Conclusion Extreme care should be exercised during clinoidectomy. Should small vascular injury occur, direct microsuturing can be a good alternative to sacrificing or implantation anastomosis repair.

Perigraft seroma after total aortic arch replacement using Triplex graft

xlomafota.13 shared this article with you from Inoreader Perigraft seroma after total aortic arch replacement using Triplex graft Via Latest Results for General Thoracic and Cardiovascular Surgery Abstract A 42-year-old gentleman underwent total aortic arch replacement with Triplex graft (Terumo corporation, Tokyo, Japan) for acute type A dissection. Sixteen months later, a computed tomography revealed a rapidly enlarging low-density area around the graft, with no contrast enhancement. The area was compressing the mediastinal structures, such as the superior vena cava and right pulmonary artery. Suspecting lymphorrhea or perigraft seroma (PGS), surgical drainage was performed. Although fluid accumulation around the graft was cloudy and yellowish, Gram stain was negative. A fatty preparation was administered from the nasogastric tube, demonstrating no leakage of chyle. Intraoperative lymphangiography with indocyanine green also showed no lymphatic leak. Therefore, PGS was suspected. Fibrin glue was applied to the graft and the surgery was completed. PGS drainage after arch replacement, especially with Triplex graft, is extremely rare. We discuss the strategies of di agnosis and treatment for this uncommon complication after aortic surgery.
